AndroidX library to use animation interpolators on older platforms.
- Lifecycle (Utility)
perform actions in response to a change in the lifecycle status of another component, such as activities and fragments.
- Loader (Utility)
library to load data for your UI that survives configuration changes.
- Preference (Utility)
a library to build interactive settings screens without needing to interact with device storage or manage the UI.
- Recyclerview (Utility)
display large sets of data in your UI while minimizing memory usage.
- Android Activity Saved State (Utility)

- Transition (UI Component)
animates motion in the UI with starting and ending layouts.
- Vectordrawable (UI Component)
AndroidX library to render vector graphics.

- JavaX Dependency Injection (Utility)
specifies a means for obtaining objects in such a way as to maximize reusability, testability and maintainability compared to traditional approaches such as constructors, factories, and service locators (e.g., JNDI). This process, known as dependency injection, is beneficial to most nontrivial applications.
- Kotlin (Utility)
The Kotlin Programming Language
- kotlinx.coroutines (Utility)
library support for Kotlin coroutines.
